k8s中部署nacos
文章目录[隐藏]
k8s安装参考:http://www.duozhi.online/2023/10/20/centos7%e4%b8%adkubeadmin%e6%90%ad%e5%bb%bak8s-1-22/
mysql 安装参考:http://www.duozhi.online/2023/10/20/centos7%e5%ae%89%e8%a3%85mysql-8-0/
1.在192.168.0.205数据库中初始化数据
在205中创建nacos_config数据库

3.后续操作
修改nacos配置文件,就改nacos-cm 这个ConfigMap中的内容
数据存储在pvc中

对应在203nfs中的内容为
